> Why would 4k sector disks use any geometry at all? Disks don't "use" geometry. PC BIOS partition tables entries have multiple components. To conform to any of the somewhat inconsistent PC BIOS partition table "standards", entries have both CHS components and LBA components. Partitioning tools are what use CHS for the purpose of reading and writing conforming table entries, and very significantly, choosing partition start sectors. http://fm.no-ip.com/SS/dfsPTedit.png CHS * 64 32 is about making sure partition starting points are aligned on 4k multiples for performance reasons. http://www.seagate.com/tech-insights/advanced-format-4k-sector-hard-drives-master-ti/ -- "The wise are known for their understanding, and pleasant words are persuasive."
